These are good batteries for the price. I honestly can't argue with that. On a full charge, mine ran about a little over an hour in my 1300 round dual mag. Since I don't own a SAW of any kind, I really got my taste through the dual mag. I will leave a fair warning that I have only had this battery for a few months and it's already corroding. Possible safety hazard and it is also annoying to charge since mine didn't come with a manual when I got the dual mag. I would guess a fair charge is around 4 hours. I let mine charge over night, which might have accelerated the corrosion rate... Don't know...

Pros:
Good lengthy life span for my dual mag, (usually no ammo by the time it dies)
Goes for both SAWs and Auto-winding rifle super caps
Cheap for it's quality
Strong charge for fast and efficient winding. Never misfed once

Cons:
Corrodes quick as heck (barely made 3 months on my first)
LOOOOOOOOOOOOONG charge time... Grrrr
No smart charger that I know of so this accompanies the charge con... Some more grrrrrrrr
